About Anthropic

Anthropic’s mission is to create reliable, interpretable, and steerable AI systems. We want AI to be safe and beneficial for our users and for society as a whole. Our team is a quickly growing group of committed researchers, engineers, policy experts, and business leaders working together to build beneficial AI systems.

About the Role

At Anthropic, we're building AI systems that are safe, beneficial, and transformative. Our mission is to develop AI that benefits humanity, and we believe the most powerful capabilities emerge when we thoughtfully bridge the gap between research breakthroughs and real-world applications.

Anthropic Labs serves as our internal accelerator. We're looking for the next breakout hits that bring substantial revenue or transform an industry. We operate in close partnership with research and build through fast iteration cycles. Past successes include Claude Code and MCP.

We're seeking versatile, entrepreneurial engineers to join Labs. In this role, you'll work at the intersection of cutting-edge research and real-world application, rapidly building and testing new experiences, working directly with researchers and users, and generating the insights that shape Anthropic's product future. You'll need to be comfortable with ambiguity, willing to kill your own projects when the data says to, and energized by the pace of building in uncharted territory.

Responsibilities

• Rapidly prototype full-stack applications that showcase emerging AI capabilities, shipping early and often to maximize learning
• Collaborate closely with research teams to understand new model capabilities and translate them into intuitive user experiences
• Work directly with internal test users and external partners to gather feedback, iterate quickly, and validate (or invalidate) product concepts
• Design and run structured experiments to test hypotheses, balancing creative exploration with rigorous evaluation
• Generate documentation and insights to guide successful prototypes toward full product teams
• Advocate for user experience and product considerations early in the research process
• Provide feedback to research teams about model effectiveness and where capabilities can be improved
• Flexibly contribute across Labs initiatives based on organizational priorities and emerging opportunities-context from one project should inform the next

You May Be a Good Fit If You

• Have 8+ years of experience building full-stack applications, with a track record of zero-to-one work in startup or startup-like environments
• Thrive in ambiguity and are energized (not anxious) by uncertainty-you're comfortable working on projects that might not exist in three months
• Have a hacker mentality: high agency, bias toward shipping, comfort with technical debt when it's the right tradeoff
• Are deeply user-centric-you validate ideas with actual users before over-investing and talk about problems before solutions
• Can articulate learnings from failed or killed projects without defensiveness; you treat your work as experiments
• Hold strong opinions loosely-you advocate forcefully for ideas but change your mind based on evidence
• Are a generalist who can transition between different problem spaces as priorities shift
• Work independently with good judgment about what matters, without needing constant direction
• Communicate effectively and translate complex AI capabilities into intuitive experiences
• Care about the societal impacts and ethics of your work

What We Offer

• Annual Salary: $320,000 - $485,000 USD
• Location-based hybrid policy: Currently, we expect all staff to be in one of our offices at least 25% of the time. However, some roles may require more time in our offices.
• Visa sponsorship: We do sponsor visas! However, we aren't able to successfully sponsor visas for every role and every candidate. But if we make you an offer, we will make every reasonable effort to get you a visa, and we retain an immigration lawyer to help with this.

How We're Different

We believe that the highest-impact AI research will be big science. At Anthropic we work as a single cohesive team on just a few large-scale research efforts. And we value impact - advancing our long-term goals of steerable, trustworthy AI - rather than work on smaller and more specific puzzles. We view AI research as an empirical science, which has as much in common with physics and biology as with traditional efforts in computer science. We're an extremely collaborative group, and we host frequent research discussions to ensure that we are pursuing the highest-impact work at any given time. As such, we greatly value communication skills.

Agreement to Arbitrate

I understand and agree that both Anthropic and I waive our respective rights to trial by jury in connection with any claims covered by this agreement to arbitrate. Instead, any disputes arising out of or related to my application for employment with Anthropic shall be settled by final and binding arbitration pursuant to the Federal Arbitration Act. I understand and agree that Anthropic’s employees/agents, Anthropic’s clients, and their employees/agents are third-party beneficiaries to this agreement.

The arbitration shall be conducted in accordance with the Employment Arbitration Rules & Procedures of Judicial Arbitration and Mediation Services, Inc. (“JAMS Rules”), available via the internet at https://www.jamsadr.com/rules-employment-arbitration or by searching for “JAMS Employment Arbitration Rules” in an online search service such as www.google.com*. To the extent the JAMS Rules are inconsistent with the terms of this Agreement, this Agreement shall govern to the extent permitted by law. The parties will select one neutral arbitrator, who will have the authority to award all relief in law or equity that is requested by the parties and supported by credible, relevant, and admissible evidence. The arbitrator shall allow adequate discovery and issue a written, signed, and reasoned award. Judgement may be entered on the arbitrator’s award in any court having jurisdiction, and the award shall be subject to correction, confirmation, or vacation as provided by the applicable law concerning judicial review of arbitration awards. Anthropic will bear the costs that are particular to the arbitration, such as the arbitrator fees. The arbitrator will apply the substantive law of the state in which I sought employment with Anthropic. The arbitrator will determine the arbitration venue, based on fairness and convenience to the parties and witnesses, unless otherwise mutually agreed upon by the parties. The Party initiating a claim under this Agreement must make a written demand for arbitration to the other Party. The demand for arbitration shall identify the claims asserted, the facts upon which such claims are based, and any relief or remedy sought. Written demand for arbitration to Anthropic must be sent to Anthropic PBC at* [email protected]*. Anthropic’s demand for arbitration shall be sent to the most recent mailing address and/or email address that Anthropic has on file for you.*

This agreement to arbitrate does not apply to claims for workers’ compensation, unemployment compensation benefits, claims or charges before any administrative agency having jurisdiction over such claims, or any other claim that is not subject to arbitration under federal law. If any claims are deemed non-arbitrable, then those claims will be stayed until resolution of any arbitrable claims.

I understand and agree that, except where prohibited by federal law, all claims subject to this agreement to arbitrate must be pursued on an individual basis, and that both I and Anthropic waive any right to bring or be a party to any class or collective action. I agree that any issues pertaining to the enforceability, application or validity of this agreement to arbitrate shall be decided only by a court of competent jurisdiction and not by an arbitrator. This agreement to arbitrate applies only in the United States.
